APPARATUS FOR DRYING SHINGLES.

SPECIFICATION forming part of Letters Patent No. 228,464, dated J1me 8, 1880.

Application filed October 23, 1879.

To all whom at may concern:

Be it known that I, WILLARD A. KITTS, 0f Oswego, in the county of Oswego, in the State of New York, have invented new and useful Improvements in Apparatus for Drying Shingles, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

The purpose of this invention is to dry shingles, and thus prevent stain and decay of same, and relieve them of superfluous weight and the consequent extra expense of transportation.

In the accompanying drawings, Figure 1 is a side elevation of my invention; Fig. 2, a longitudinal section of same; Fig. 3, a front elevation, and Fig. 4 a transverse section through the center of the drying-chamber.

Similar letters of reference indicate corresponding parts.

The apparatus is designed to be used in connection with the shin gle-factory, and utilize the shavings and offal of the shingles as fuel for heating the air required for drying the shingles.

A represents a furnace, which, for the purpose of saving the extra labor of feeding the fuel, is located at a safe and convenient distance from the shin gle-factory, and at the point where usually the oifal is deposited and burned.

The furnace consists of an iron chamber provided with a grate at the bottom and a hopper or feed-funnel, B, at the top, through which the fuel is introduced and the smoke is emitted. The fuel is conveyed thereto by scrapers connected to endless chains extended from the shingle-factory to the depository, as indicated by dotted lines in Fig. l of the drawings, or by such other means as may be adapted or deemed expedient for a convenient and expeditious disposition of the offal.

The furnace is surrounded by a casin g joined therewith at the base and top on all sides, 'and forming an air-passage around it.

The air is admitted through one or more apertures, a, at the base of the outer casing, and in its circulation between the said casing and furnace it becomes heated, and thence passes through a pipe, 1?, into the chamber D, containing the shingles to be dried.

In order to carry on the drying process uninterruptedly, I employ two or more dryingchambers, D, separated from each other by air-tight partitions b, and connect to the hotair pipe 1 branch pipes 1?, communicating with the respective drying-chambers at the bottom thereof, and provided with dampers d,

for changing the current of hot'air from one drying-ehamber to the other.

E E are the hot-air-exit pipes, connected to the top of the drying-chambers, respectively,

and communicating with a draft-flue, F. Each of the said pipes E is provided with a damper, e, by which the egress of air can be controlled.

For the purpose of thoroughly distributing the hot air in the drying-chambers D, I provide the said chambers with two horizontal perforated diaphragms, f and 7', one being near the bottom and above the ingress of the hot air, and constituting the floor upon which the shingles to be dried are supported. The other diaphragm is near the top and sufficiently distant from the exit to allow the hot air to circulate between the said diaphragm and top of the chamber.

The apparatus is operated as follows: The hot air is excluded from the drying-chamber designed to be filled by closing the dampers of the inlet-pipe I? and the exit-pipe E, and the shingles are introduced through the door g and piled upon the perforated floor j. After the drying chamber is filled the door 9 is closed and the dampers in the hot-air inlet and exit pipes opened. WVhile one of the chambers is thus in operation the other chamber can be emptied and refilled, and the process of drying shingles carried on uninterruptedly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination of the furnace A, provided at its top with the feed-funnel B, a casing surrounding the furnace, and provided at its base with the aperture to, the pipes I? and P, the latter provided with dampers d, and communicating with the drying-chambers D D at the bottom thereof, the dryingchambers separated from each other by airtight partitions, the exit-pipes E, provided with dampers e, and communicating with the draft-flue F, all combined and arranged substantially in the manner described and shown,

for the purpose set forth.

In testimony whereof I have hereunto signed my name and affixed my seal in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga and State of New York, this 17th day of October, 1879.
